A thermal printer roll is a type of paper, also known as thermal receipt printer paper, used in thermal printers to produce high-quality, long-lasting printouts. They are coated with a particular material that reacts to heat, creating a sharp and clear print. They are commonly used to print invoices, receipts, shipping labels, and other types of point-of-sale and transaction documents. Their heat-sensitive properties ensure that the print will not fade or fade, making them ideal for high-volume printing in various industries, including retail, healthcare, and logistics.
